describe the graph that would be used to solve
the equation -x2 + 4 = x + 2 using a system of
equations. how will you use the graph to find the
solution(s)?

A quadratic graph whose equation is

x2 + x - 2

Step-by-step explanation:

Firstly create your equation by moving all variables to one sidex2 + x + 2 - 4.

Then after drawing the graph...the solutions to the equation are the points at which the graph intercepts with the x-axis of the cartesian plane

4 and 5)16.97 or 12√2

6)15.59 or 9√3

7)y = 15.59 or 9√3     x =27

8)17.80

step-by-step explanation:

circumference divided by 3.141592654 then timesthe radius twice
